To shut down your instrument completely:
CAUTION
The ICP-OES gas control unit supplies uninterrupted gas purge to the
polychromator assembly during the run and idle states only to minimize the
ingress of moisture. It is recommended that both the instrument and gas
supplies be left on at all times except during long periods of non-use.
1 Follow Steps 1-7 of the Standby Mode procedure.
2 Switch off any accessories (where applicable), and then shut down the argon
gas supply at the cylinder.
3 Switch off the power at the front lower left of the instrument.
4 Wait for the front power on/off switch green LED to stop blinking and then
switch off the mains power switch on the left side of the instrument. This will
turn off the complete instrument as well as the polychromator thermostatting
system.
5 Turn off the laboratory exhaust system.
6 Exit the ICP Expert software, if it is no longer required, by choosing Exit from
the File menu. Switch off the printer and monitor.
Restarting the instrument to be ready for analysis again will take several hours due
to the gas purge and polychromator thermal stabilization time. See Page 40 for full
start up instructions.
NOTE
If the instrument is not going to be in use for a period of time the torch, cone, snout
and torch compartment should be cleaned of any deposits, dirt or residue. Check
the cleanliness of the removable axial window when cone is removed.
